I tried Vista on release day and i thought it was crap... explorer.exe was like a **cannot find language appropriate for these forums**.. every time you asked it to do anything there was that green flowing bar of death.. and when vista tried to automatically shuffle folders when you renamed them had some sort of mutant lag on it where a different file gets renamed and all sorts of weird stuff... and i was afraid to open some of my larger folders cas of how sad it ran... how can opening folders rattle a 3ghz core2duo - 4GB - WD RE2 hdd... but erm bout 2 weeks ago I isntalled Vista Ultimate x64 SP1... and like wow! I've only encountered two bugs... one with nero and when I create an ISO from files on my hdd.. the speed starts of 70,000KB/s but after not long grinds down to under 1,000KB/s... but i guess thats nero anyways (as changing software fixes it)... the other bug I've come across is using Remote Desktop Connection to view an XP Pro machine i get garbage on the screen... see screenshot here (note: the software involved in this screenshot is not the only text affected, explorer windows are among others) this never happened using XP x64 Pro to view this same XP 32 Pro machine... sometimes words will be replaced with other words found somewhere else in the desktop (same words but new font appropriate to where they appear).. really weird.. but this does not affect any data totally a cosmetic error.. Other than that and playing Crysis on DX10/Very High/1680x1050 @ 18-28fps which is verry upsetting indeed.... I lurrrv Windows Vista x64 Ultimate SP1 now...
